SITE NAME DATA POINT
AVERAGE YEARLY BRIGHT SUNSHINE HOURS (BSH)
ADJUSTED (+ or - a +5 percent) TOTAL BSH
AVERAGE PEAK HOURS PER DAY (total BSH x 0.0017) = B =
AVERAGE ANNUAL TEMPERATURE (at monitor point) c =
ADJUSTED FOR SITE (c - adiabatic lapse rate) +20 = C =
DUTY CYCLE (shown as a decimal, eg. 8% = .08) = dc =
TOTAL DAILY NORMAL OPERATING HOURS a = h
TOTAL STANDBY CURRENT (24 x Rx(I)) = b = Ah
TOTAL TX CURRENT (a x Tx(I) x dc) = c = Ah
TOTAL DAILY REQUIREMENT (b + c) = r = Ah
REPEATER OPERATING VOLTAGE V = Volts
BATTERY TYPE VOLTS PER CELL v = Volts
NUMBER OF CELLS REQUIRED IN SERIES (V/v) = VI = cells
ONE BANK OF CELLS WILL GIVE (100 / r) DAYS OF STORAGE
CHARGE VOLTAGE PER CELL CV = Volts
REVERSE CURRENT DIODE OR REGULATOR LOSS D = Volts
NOMINAL PANEL VOLTAGE (from manufacturers data) = m = Volts
PANEL O/P VOLT REQ’D (D+R+(VIxCV)+(0.004(C x m))) = L = Volts
PANEL CURRENT (from man. power graph) at L volts = M = A
MODULE CURRENT PER DAY (B x M) = M1 = A
NUMBER OF PANELS REQUIRED = (r / M1) = modules
